[0047]FIG. 1 through FIG. 5 illustrate altogether the basic structure ofthe invention thermostatic automatic cutoff charging device allowing fora variety of alternate matching circuits of which a few examples will bedealt with next to demonstrate rather than to limit the scope ofapplication that is possible with any embodiment executed according tosaid basic structure, referring to FIG. 6, illustration of one exampleof the invention usually closed thermo-sensitive circuit breaker withheat retention resistor as executed beside the rechargeable cell, it isseen that structurally this embodiment comprises:

[0048] Heat retention resistor R1 which consists of one or more fixed orvariable resistor or Positive Temperature Coefficient (PTC) or NegativeTemperature Coefficient (NTC) resistor, or still of two or moredifferently characterized resistors in serial or parallel or compoundserial/parallel combination, and that made in parallel with the usuallyclosed thermo-sensitive circuit breaker TS1 to account for a symbioticenclosure PK1, or alternatively both be made adjacent to each other andhoused in a totally sealed or half sealed chamber in the form of athermocouple, meantime symbiotic with the rechargeable cell B1 on thehousing H102, as a thermocouple beside the Rechargeable Cell, and thatstill forming a couple with a structural compartment beside the chargingpower supply together with the charging power supply circuit and thecharging power side housing H101 by the intervention of conductivecontacts or plug/socket assembly, the coupling is made active when thecharging is taking place, the heat retention resistor R1 is parallelledacross and thermo-coupled to the usually closed ends of the usuallyclosed thermo-sensitive circuit breaker TS1 in order to be in serieswith the rechargeable cell B1, complete with conductive contacts orplug/socket assembly P1, P2 charging mounts, or in direct conductionwith the D.C. power supply, or the charging mount may be saved byguiding the conductive contacts or plug/socket assembly P1, P2 or thecoupling straight to the D.C. power supply, such that when therechargeable cell B1 is charged to saturation concurrent with release ofheat so that the usually closed thermo-sensitive circuit breaker TS1becomes open, the heat retention resistor R1 will produce heat becauseof a topping current present in the rechargeable cell, whereby theusually closed circuit breaker TS1, by the action of the heat thusgenerated, is maintained open, the impedance on the part of the heatretention resistor R1 will suffice to restrict the level of the toppingcurrent inherent with the rechargeable cell B1; across both ends of theusually closed thermo-sensitive circuit breaker TS1 may be installed adisplay ID1 in parallel serving to convert electric energy into audiosignals or optic signals by the incorporation of voltage restrictor orcurrent divisor to that purpose;

[0049] Arrangement of the above-mentioned display and associated voltagerestrictor, current divisor as an option to the subject thermostaticautomatic cutoff charging device may be in addition to or supplementedwith a conventional design conductive contact protector SP1 so as toinhibit electromagnetic interference and to protect the conductivecontacts justified in the presence of currents prevailing once theconductive contacts on the usually closed thermo-sensitive circuitbreaker are cut off;

[0050] Charging power supply being in the form of a common D.C. powersupply or of a D.C. power supply by rectification of an A.C. source;

[0051] Rectifier RC100: whereby a single phase, multiple phase, orcenter tapped A.C. power source is rectified to be a full-wave orhalf-wave D.C. output; essentially a diode or bridge rectifier.

[0052] An example of the invention by the addition of an auxiliaryresistor to the circuit illustrated in FIG. 6, is shown in FIG. 7, whichis in the form of an auxiliary resistor Z1 executed from one or morefixed or variable resistor or Positive Temperature Coefficient (PTC) orNegative Temperature Coefficient (NTC) resistor, or alternatively fromtwo or more differently characterized resistors in series or parallelconnection or still in compound serial/parallel combination, and thatfor parallelling across the charging power supply, meantime forming asymbiotic enclosure PK1 together with heat retention resistor R1 andusually closed thermo-sensitive circuit breaker, or alternativelyadjoinly collocated in a fully sealed or half sealed enclosure toaccount for thermo-coupling, whereby supplemental heat is produced in aninstance of charging at low temperature, and that achieving alleviationof impacts due to low temperature environments on operation points ofthe usually closed thermo-sensitive circuit breaker TS1; where therechargeable cell B1 and the charging power supply are intervened bytriplicate interfacing conductive contacts or plug/socket assembly P1,P2 and P3, then one end of the auxiliary resistor Z1 will be connectedto the negative polarity of the rechargeable cell B1, or alternativelyto the positive polarity thereof (or still to the negative polarity ofthe rechargeable cell B1 which is already in series with a usuallyclosed thermo-sensitive circuit breaker), while the other end of same isconnected by way of conductive contacts or plug/socket assembly P3 tothe other end of the opposite polarity on the charging power supplyside, so as to offer temperature compensation in different temperatureenvironments, in addition, to prevent the rechargeable cell B1 fromdischarging in the reverse direction by way of auxiliary resistor Z1,insulation may be provided by selectively installed insulation diode CR2to meet circuit actualities, in either manner prescribed below:

[0053] 1. the diode CR2 as provided in forward series way between thepower supply side of the auxiliary resistor Z1 and the side of the A.C.power supply enabling the rectifier RC100 from which the output is D.C.,that in order for the auxiliary resistor Z1 to acquire the D.C. powersupply in need and serving at the same time to prevent reverse dischargeof the rechargeable cell B1;

[0054] 2. the diode CR0 as provided in forward series way between thepower supply end of the auxiliary resistor Z1 and that in common withthe D.C. output terminal of the rectifier RC100 to which the input isthe charging power supply, and that going eventually to the chargingpower side of the conductive contact or plug/socket assembly P1, servingto prevent reverse discharge from the rechargeable cell B1.

[0055] Apart from being connected straight to or parallelled to thecharging power supply across conductive contacts or plug/socketassembly, like what is shown schematically in FIG. 7, the auxiliaryresistor Z1 can be made in series with the heat retention resistor R1 asillustrated in FIG. 8, before being parallelled with the D.C. powersupply. FIG. 8 shows schematically an example in which an auxiliaryresistor is connected in series with the heat retention resistor as anaddition incorporated to the circuitry shown in FIG. 7, according to theinvention; where justified in a case, the auxiliary resistor Z1 may bemounted on the load side or on the charging power supply side, in FIG. 9is shown an example whereof the auxiliary resistor that is added to thecircuit shown in FIG. 7 is mounted on the side of the charging powersupply, in parallel across the positive polarity of the charging powersupply and may just as well account for a circuit associated with thenegative polarity of the rechargeable cell; also, with a view to yieldbetter thermocouple effects, as a preferred alternative to theabove-mentioned instances whereby the heat retention resistor R1 is madesymbiotic with the usually closed thermo-sensitive circuit breaker TS1on a common enclosure PK1, or alternatively on a fully sealed orhalf-sealed enclosure, it is feasible to mount the auxiliary resistorZ1, the heat retention resistor R1 and the usually closed circuitbreaker TS1, as close by the rechargeable cell, symbiotically onto acommon enclosure PK1, or alternatively into a tightly sealed orpartially sealed chamber; in FIG. 10 is shown an example whereof theinvention is represented in a circuitry comprising the auxiliaryresistor, the heat retention resistor and the usually closedthermo-sensitive circuit breaker installed symbiotically on the side ofthe rechargeable cell, as an addition incorporated to what isrepresented in FIG. 7.

[0056] The examples illustrated in FIG. 6 through FIG. 10 are common inthat the usually closed thermo-sensitive circuit breaker is installedonto the rechargeable cell, where structurally justifiable, however, itis also possible for the usually closed thermo-sensitive circuit breakerto be mounted on the charging power supply side and that thermocouple isconsummated with the rechargeable cell when loaded into the rechargeablecell.

[0057]FIG. 11 illustrates the invention usually closed thermo-sensitivecircuit breaker with heat retention resistor embodied by mounting to thecharging power supply side, the structure as shown comprises:

[0058] Heat retention resistor R1, as in the form of one or more fixedor variable resistor or Positive Temperature Coefficient (PTC) orNegative Temperature Coefficient (NTC) resistor, or in the form of twoor more differently characterized resistors connected in series orparallel or in compound serial/parallel combination, and that inparallel with the usually closed circuit breaker TS1 to account for asymbiotic enclosure PK1, or alternatively both conjointly laid out in afully sealed or partially sealed chamber and in that mannerthermo-coupled to each other, collocated with the charging power supplycircuit in the charging power supply side housing H101 to make for acharging power supply side structure, integral with the rechargeablecell side structure which consists of the rechargeable cell B1 and thehousing H102, mutually thermo-coupled when in a state of chargingoperation, or as executed otherwise when so dictates a specificapplication, the heat retention resistor R1 is in parallel with andthermo-coupled to the usually closed contacts on the usually closedthermo-sensitive circuit breaker TS1 before being connected in serieswith the charging power supply only to come into conduction with therechargeable cell B1 as loaded by way of conductive contacts orplug/socket assembly, once the rechargeable cell B1 is charged tosaturation and that accompanied with the production of heat, and of athermocouple which eventually breaks the usually closed circuit breakerTS1 open, occasioned by the passing of a topping current released fromthe rechargeable cell B1, through the heat retention resistor R1, theimpedance owing to the same very heat retention resistor R1 will serveto restrict the current that is being maintained in the rechargeablecell B1 as previously referred to as a topping current; across both endsof the usually closed thermo-sensitive circuit breaker TS1 may beoptionally installed a display ID1 in parallel, into which electricenergy is converted into audio or video signals, complete with necessaryvoltage restriction or current division means;

[0059] Said display together with relevant voltage restriction orcurrent division means integral with the thermostatic automatic cutoffcharging device prosecuted according to the invention, serving to advisecompletion of a charging operation may optionally incorporate a priorart contacts protection means SP1 to inhibit electromagneticinterference and protect conductive contacts unaffected by currentsprevailing once the conductive contacts at the usually closedthermo-sensitive circuit breaker get broken;

[0060] Charging power supply, supplied as common D.C. power source orone D.C. power source derived from a rectified A.C. source;

[0061] Rectifier RC100: a diode or bridge rectifier whereby single phaseor multiple phase A.C. source or center tapped A.C. source is rectifiedinto full-wave or half-wave D.C. power supply.

[0062] What is shown in FIG. 12 is an example of the circuit representedin FIG. 11 incorporating in addition an auxiliary resistor circuit bythe intervention of one auxiliary resistor Z1 which comprises one ormore Positive Temperature Coefficient (PTC) or Negative TemperatureCoefficient (NTC) resistor, of a fixed or variable value, oralternatively two or more differently characterized resistors in serialor parallel or compound serial/parallel combination and an optional,serially connected power indicator L200, and that made in parallel withheat retention resistor R1 and the usually closed thermo-sensitivecircuit breaker TS1 to account for a symbiotic enclosure PK1, oralternatively both being conjointly housed in a tightly sealed orpartially sealed space and thermo-coupled to each other, wherebyauxiliary heat is produced in a case of charging at lower temperatureambience so that impact due to a lower ambience upon operation ofusually closed thermo-sensitive circuit breaker TS1 is kept to theminimum; where conductive contacts or plug/socket assembly P1, P2 withtwo conductive interfacings are mounted way between the rechargeablecell B1 and the charging power supply, to offer temperature compensationin environments dissimilar in temperature conditions, the remedy is tohave one end of the auxiliary resistor Z1 connected to the negativepolarity of the power supply, or positive polarity (or still to thenegative polarity of the rechargeable cell to which a serial connectionhas been made with the usually closed thermo-sensitive circuit breaker),and to have the other end thereof connected to the other end of theopposite polarity on the rechargeable cell B1, besides, to prevent therechargeable cell B1 from discharging in the reverse direction by way ofthe auxiliary resistor Z1 insulation may be secured by the incorporationof an insulation diode CR2, more specifically:

[0063] 1. the diode CR2 as provided in forward series way between thepower supply side of the auxiliary resistor Z1 and the side of the A.C.power supply enabling the rectifier RC100 from which the output is D.C.,that in order for the auxiliary resistor Z1 to acquire the D.C. powersupply in need and serving at the same time to prevent reverse dischargeof the rechargeable cell B1;

[0064] 2. the diode CR0 as provided in forward series way between thepower supply end of the auxiliary resistor Z1 and that in common withthe D.C. output terminal of the rectifier RC100 to which the input isthe charging power supply, and that going eventually to the chargingpower side of the conductive contact or plug/socket assembly P1, servingto prevent reverse discharge from the rechargeable cell B1.

[0065] In addition, instead of having the auxiliary resistor Z1parallelled straight to the charging power supply or by way ofconductive contacts or plug/socket assembly to same charging powersupply, like what is shown in FIG. 12, an alternative approach is asshown in FIG. 13, having a power indicator L200 installed in series withdiode CR2 and auxiliary resistor Z1 where needed, only to be parallelledin suit to one end of the A.C. power supply and to the opposite polarityon the D.C. output terminal of the rectifier RC100 (with the exampleshown in FIG. 13 it is the negative polarity terminal), to therebysupply current to the display ID1, the display ID1 may where justifiedbe parallelled with a current splitting resistor RS; across both ends ofthe heat retention resistor R1 may be installed in reverse direction adiode CR101 relative to the trickle current ongoing all the times, so asto bypass the current coming from the auxiliary resistor Z1 when theusually closed thermo-sensitive circuit breaker TS1 is closed so thatcurrent feeding to the display ID1 is suspended, the display ID1 that isbound with necessary voltage restriction or current splitting elementsis in series with the heat retention resistor R1 before parallellingacross both ends of the usually closed thermo-sensitive circuit breakerTS1, so that in the event temperature in the usually closedthermo-sensitive circuit breaker TS1 rises to a critical point such thatthe contact is broken open, the electric energy may by way of theauxiliary resistor Z1 drive the display ID1 that is being bound withrequired voltage restriction or current division means;

[0066] The invention thermostatic automatic cutoff charging deviceconfigured with aforementioned display and relevant voltage restrictionand current splitting means, by the split current occasioned onresetting of the contacts on the usually closed thermo-sensitive circuitbreaker as it cools off, to closure, once the rechargeable cell B1 iswithdrawn, power to the display ID1 that is already bound with voltagerestriction or current splitting means is suspended forthwith; anexample of the circuitry of auxiliary resistor with display incorporatedin series with the schematics shown in FIG. 11 is illustrated in FIG.13.

[0067] Similarly, in the examples shown in FIG. 11 through FIG. 13, tosecure a better thermo-coupling compensation addressed to convectivedifferential as a function of utility environments as well as structurallayout, an alternative approach to the aforementioned execution of asymbiotic enclosure PK1 or a tightly sealed, partially sealed chamberhousing said heat retention resistor R1 and usually closedthermo-sensitive circuit breaker TS1, is to collocate the auxiliaryresistor Z1 that is installed beside the charging power supply as do theheat retention resistor R1 and the usually closed thermo-sensitivecircuit breaker TS1 on a common structure, or in a tightly sealed, orpartially sealed enclosure PK1.

[0068] In the embodiment of circuitry shown in FIG. 14 whereof theusually closed thermo-sensitive circuit breaker is installed beside therechargeable cell, and the heat retention resistor installed beside thepower supply, the structure comprises; as shown in the accompanyingdrawings:

[0069] Heat retention resistor R1, in the form of one or more fixed orvariable resistor, or positive temperature Coefficient (PTC) or NegativeTemperature Coefficient (NTC) resistor, or still of two or moredifferently characterized resistors connected in series or parallel orstill prosecuted in compound serial/parallel combination, mounted besideand in series with the charging power supply, and made integral with thecharging power supply circuit and the charging power supply compartmentH101; whereas the usually closed thermo-sensitive circuit breaker TS1 ismade in series with the rechargeable cell B1 and as lying beside it,integral with the housing H102 for the rechargeable cell B1, the heatretention resistor R1 and the usually closed thermo-sensitive circuitbreaker TS1 are parallelled straight or by way of conductive contacts orplug/socket assembly P1, P2, P3 when the structures on which both arebound are combined together, as confined in the space created in theform of a totally or partially sealed chamber when the combination takesplace, with the heat retention resistor R1 mounted on the charging powersupply side, the usually closed thermo-sensitive circuit breaker TS1mounted on the rechargeable cell side, both will combine in parallel toform a thermocouple when a charging is taking place; once therechargeable cell B1 reaches saturation concurrent with production ofheat such that the usually closed thermo-sensitive circuit breaker TS1is driven open, heat will be generated on the heat retention resistor R1due to the topping current coming from said rechargeable cell, therebycompelling, by the thermocouple thereupon produced, the usually closedthermo-sensitive circuit breaker TS1 into an open condition, meanwhilethe impedance on the heat retention resistor R1 serves to set a limit tothe level of the topping current originating from the rechargeable cellB1; both ends of the usually closed mode of the usually closedthermo-sensitive circuit breaker TS1 beside the rechargeable cell, orthose both ends of the heat retention resistor beside the charging powersupply may optionally parallelled with a display ID1 whereby electricenergy may be converted into audio or video signals, and whichincorporates required voltage restrictor or current splitting means, oralternatively such a display ID1 may be made in series with the heatretention resistor R1, or where preferred, initially in parallel with acurrent splitting resistor RS only to be in series with the HeatRetention Resistor R1, before being parallelled across both ends of theusually closed thermo-sensitive circuit breaker TS1, to indicatecompletion of a charging operation, or still a prior art conductivecontact protection means SP1 may be incorporated additionally to inhibitelectromagnetic interference due to current prevailing once theconductive contacts on the usually closed thermo-sensitive circuitbreaker are cut open, and to protect such conductive contactsthemselves;

[0070] Charging power supply, being a conventional prior art D.C. powersupply or one D.C. source converted from a regular A.C. source throughrectification;

[0071] Rectifier RC100: whereby single phase or multiple phase A.C.power source or center-tapped A.C. source is rectified into full-wave,half-wave D.C. form, and executed as a rectification diode or bridgerectifier.

[0072] An example of the circuit that is represented in FIG. 14 with theaddition of an auxiliary resistor circuit, prosecuted according to theinvention, is shown in FIG. 15, which is in fact the incorporation ofone auxiliary resistor Z1 which consists of one or more PositiveTemperature Coefficient (PTC) or Negative Temperature Coefficient (NTC)resistor, or two or more differently characterized resistors in serialor parallel connection or compound serial/parallel combination to thatstructure close by the charging power supply mounted close to theusually closed thermo-sensitive circuit breaker beside the rechargeablecell, and the meant for parallelling with the charging power supply, andsuch that when combined with the usually closed thermo-sensitive circuitbreaker TS1, a thermocouple is made structurally in the totally sealedor partially sealed space confined by the common structure, to theeffect that auxiliary heat is produced when a low temperature chargingis taking place, so as to minimize the impact by a low temperaturecharging environment upon operation of the usually closedthermo-sensitive circuit breaker TS1.

[0073] As an alternative approach, the auxiliary resistor Z1 may be madein series with the heat Retention Resistor R1 straight for parallellingacross the charging power supply, like what is shown in FIG. 16, withone terminal of the auxiliary resistor Z1 connected to one terminal,positive or negative, on the rechargeable cell B1, by way of thecharging power supply, the conductive contact or plug/socket assembly onthe structure beside the rechargeable cell and the charging power supplyin a course of charging operation, while the other terminal is connectedto the other end of the opposite polarity on the rechargeable cell B1 byway of the conductive contact or plug/socket assembly, so as to offertemperature compensation in a low temperature charging environment, inaddition, to prevent the rechargeable cell B1 from reverse charging tothe auxiliary resistor Z1, an insulation diode CR2 may be incorporatedif needed to achieve insulation purposes, including:

[0074] 1. the forward serial incorporation of an insulation diode CR2way between the power supply end of the auxiliary resistor Z1 and theA.C. power outlet of the rectifier RC100 installed to yield a D.C. powersupply, so as to provide the auxiliary resistor Z1 with the D.C. sourceit needs while serving also to prevent reverse discharging of therechargeable cell B1;

[0075] 2. the forward serial incorporation of an insulation diode CR0way between the power outlet end of the auxiliary resistor Z1 and theD.C. output end of the charging power supply through the rectifierRC100, passing from such common contacts to the charging power side ofthe conductive contact or plug/socket assembly P1, serving to preventthe rechargeable cell B1 from reverse discharging. An example of theincorporation of an auxiliary resistor with the heat retention resistorin series before being parallelled with the charging power supplycircuit to the circuitry represented in FIG. 14 is shown in FIG. 16.

[0076] In the examples represented in FIG. 14 through FIG. 16, theusually closed thermo-sensitive circuit breaker is invariably installedbeside the rechargeable cell, and the heat retention resistor beside thecharging power supply, where structure so dictates, however, it ispermissible to have the usually closed thermo-sensitive circuit breakerbeside the charging power supply, and to have the heat retentionresistor installed beside the rechargeable cell, such that therechargeable cell is driven to form a thermocouple once loaded in acharging condition.

[0077] In FIG. 17 is shown an example of the invention wherein theusually closed thermo-sensitive circuit breaker is installed by thecharging power supply side, and the heat retention resistor installed bythe rechargeable cell side, structurally comprising:

[0078] Heat retention resistor R1, being in the form of one or morefixed or variable resistor or Positive Temperature Coefficient (PTC) orNegative Temperature Coefficient (NTC) resistor, or of two or moredifferently characterized resistor in serial or parallel connection orin compound serial/parallel combination, when united with the usuallyclosed thermo-sensitive circuit breaker TS1 by conductive contact orplug/socket assembly parallelling, into a common embodiment, mutualthermocouple will be formed in the totally or partially sealed spacetherein created, with the usually closed thermo-sensitive circuitbreaker TS1 and the charging power supply both accommodated in thehousing by the charging power side H101, the Heat Retention Resistor R1will form another entity together with rechargeable cell B1 and thehousing H102, such that in a state of charging operation the usuallyclosed thermo-sensitive circuit breaker TS1 sets itself in athermocouple with the heat retention resistor R1, or the thermocouplemay be executed otherwise as needed, the Heat Retention Resistor R1,installed on the principle that once a charging operation is in action,the conductive contacts or plug/socket assembly structurally integraltherewith are in parallel with and thermo-coupled to both ends of theusually closed thermo-sensitive circuit breaker TS1, the usually closedthermo-sensitive circuit breaker TS1, in series with the charging powersupply, is conductive with the rechargeable cell B1 as loaded in ahousing therefor provided by way of conductive contacts or plug/socketassembly, such that with the rechargeable cell B1 being charged tosaturation concurrent with release of heat, the thermocouple thereuponformed will compel the usually closed thermo-sensitive circuit breakerTS1 open, whereupon the heat retention resistor R1, by the passing of atopping current originating from the rechargeable cell B1, will produceheat and, by the thermocouple active, maintain the usually closedthermo-sensitive circuit breaker TS1 in a heat-induced open state,meanwhile the heat retention resistor R1 by its impedance will restrictthe topping current released by the rechargeable cell B1; across bothends of the usually closed thermo-sensitive circuit breaker TS1 by thecharging power side, or those of the heat retention resistor R1 besidethe cell, may be optionally installed with a display means ID1 capableof converting electric energy into audio or video signals andincorporating necessary voltage restriction or current splitting means,said display ID1 may be in series with the heat retention resistor R1,or alternatively in parallel with splitting resistor RS before connectedin series with the heat retention resistor R1, then parallelled acrossthe usually closed thermo-sensitive circuit breaker TS1, serving toindicate completion of a charging operation, or still furtherincorporating a prior art conductive contact protector SP1 to inhibitelectromagnetic interference occasioned by the current arising on cutoffof the usually closed thermo-sensitive circuit breaker conductivecontact, and to protect such conductive contacts as well;

[0079] Charging power supply, being a conventional prior art D.C. sourceor one converted by rectification from a regular A.C. source;

[0080] Rectifier RC100: being a rectification diode or a bridgerectifier capable of rectifying single phase or multiple phase orcenter-tapped A.C. source into a full-wave, half-wave D.C. output.

[0081] An example of the circuit of auxiliary resistor schema asincorporated to the circuitry represented in FIG. 17 is shown in FIG.18, which is, in execution, an auxiliary resistor Z1 composed of one ormore fixed or variable resistor or Positive Temperature Coefficient(PTC) or Negative Temperature Coefficient (NTC) resistor, or instead twoor more differently characterized resistors in serial or parallelconnection or still compound serial/parallel combination, in parallelwith the charging power supply, and in that manner forming a compositeenclosure PK1 with the usually closed thermo-sensitive circuit breakerTS1, or alternatively let the usually closed circuit breaker TS1 asestablished in the charging power supply side structure and the heatretention resistor R1 as established in the rechargeable cell sidestructure be conjointly accommodated in the fully sealed or partiallysealed chamber when both are combined together, thereby thermallycoupled, so that auxiliary heat is produced in a low temperaturecharging environment so as to minimize impact due to a low temperatureenvironment upon the operation of the usually closed thermo-sensitivecircuit breaker, in addition, to prevent the rechargeable cell B1 fromdischarging reversely by way of the auxiliary resistor Z1, insulationmay be prosecuted by the incorporation of an insulation diode CR2, as anoption, in the circuitry, more specifically;

[0082] 1. let an insulation diode CR2 be provided forwardly way betweenthe power supply end of the auxiliary resistor Z1 and the A.C. terminalto the Rectifier RC100 through which D.C. power is supplied so that theD.C. required by the auxiliary resistor Z1 is procured, while servingalso to prevent reverse discharging from the rechargeable cell B1;

[0083] 2. the forward serial incorporation of an insulation diode CR0way between the power outlet end of the auxiliary resistor Z1 and theD.C. output end of the charging power supply through the rectifierRC100, passes from such common contacts to the charging power side ofthe conductive contact or plug/socket assembly P1, serving to preventthe rechargeable cell B1 from reverse discharge.

[0084] As an alternative to being parallelled straight with the chargingpower supply, such as is shown in FIG. 18, the auxiliary resistor Z1 maybe made in series with the usually closed thermo-sensitive circuitbreaker TS1, then parallelled across the D.C. charging power supply, anexample of this exemplified in FIG. 17 is illustrated in FIG. 19.

[0085] By and large, in addition to a positive/negative pinninginterface facilitating delivery and input of electric energy featured ina common rechargeable cell specification, there is one triplicatepinning interfacing structure by the addition of a usually closedthermo-sensitive circuit breaker TS101 with a view to expand itsapplication, this thermostatic automatic cutoff charging device may havea usually closed thermo-sensitive circuit breaker TS1 and relevantcircuits installed in the charging power side structure, to account fora dual purpose circuit, serving as a charging/rechargeable cell batterycompatible with either the dual pinning or triplicate pinninginterfacing structure as afore-mentioned, permitting coupling straightor by way of conductive contacts or plug/socket assembly with therechargeable cell B1 to achieve thermo-sensitized cutoff once thecharging reaches saturation, while it may just as well be compatiblewith or matched to a rechargeable cell B1 which is already complete witha usually closed thermo-sensitive circuit breaker TS101 for the purposeof thermo-sensitized cutoff once the charging or recharging has reachedits saturation.

[0086] An example of the invention as seen in a dual purpose circuit isillustrated in FIG. 20, featuring essentially a usually closedthermo-sensitive circuit breaker TS1 on the charging power supply sidestructure in perfect thermocouple with the rechargeable cell and inseries with the charging power supply, thence parallelled by conductivecontacts or plug/socket assembly P1, P3 with rechargeable cell B1 acrossits positive/negative terminals, one serving to feed out power, anotherto feed in power, whereas the output terminal of the usually closedthermo-sensitive circuit breaker TS101 connected in series is left openshort of pinning terminal, across the usually closed thermo-sensitivecircuit breaker TS1 on both ends is parallelled a heat retentionresistor R1.

[0087] Optionally, to the structure abutting upon the usually closedthermo-sensitive circuit breaker shown in FIG. 20 is incorporated anauxiliary resistor Z1 composed of one or more fixed or variable resistoror Positive Temperature Coefficient (PTC) or Negative TemperatureCoefficient (NTC) resistor, or still two or more differentlycharacterized resistors in series or parallel connection or still incompound serial/parallel combination, plus a power indicator L200connected in series where called for in the circuitry, thenceparallelled with the charging power supply and forming a symbioticenclosure PK1 together with heat retention resistor R1 and the usuallyclosed thermo-sensitive circuit breaker TS1, or alternatively beconjointly accommodated in a totally or partially sealed chamber to runin mutual thermo-coupling, whereby auxiliary heat is produced in a lowtemperature charging environment with a view to minimize impact due to alow temperature environment upon the operation of a usually closedthermo-sensitive circuit breaker; or still the auxiliary resistor Z1 maybe made in series with the usually closed thermo-sensitive circuitbreaker TS1 thence parallelled across the D.C. charging power supply.The display ID1 featuring additional voltage restriction or currentdivision means may be optionally parallelled with a current divisionresistor RS thence made in series with the heat retention resistor R1,just for parallelling across the usually closed thermo-sensitive circuitbreaker TS1, or alternatively parallelling with the heat retentionresistor R1 is made instead with display ID1 that is driven by thenecessary voltage restrictor or current divisor, and that followed byparallelling across the usually closed thermo-sensitive circuit breakerTS1, so that once the usually closed contact should become open,electric energy can by way of the auxiliary resistor Z1 drive thedisplay ID1 to which necessary voltage restrictor or current divisor hasbeen incorporated; while bypass current which prevails when the usuallyclosed thermo-sensitive circuit breaker cools off and the contact pointresets to closure holds off its feeding to the display ID1, in addition,to prevent the rechargeable cell B1 from reverse discharging via theauxiliary resistor Z1, an insulation diode CR2 may be incorporatedoptionally to serve insulation purposes, including:

[0088] 1. the forward serial incorporation of an insulation diode CR2way between the power supply end of the auxiliary resistor Z1 and theA.C. power outlet of the rectifier RC100 installed to yield a D.C. powersupply, so as to provide the auxiliary resistor Z1 with the D.C. sourceit needs while serving also to prevent reverse discharging of therechargeable cell B1;

[0089] 2. the forward serial interpolation of an insulation diode CR0way between the power outlet end of the auxiliary resistor Z1 and theD.C. output end of the charging power supply through the rectifierRC100, passing from such common contacts to the charging power side ofthe conductive contact or plug/socket assembly P1, serving to preventthe rechargeable cell B1 from reverse discharging.

[0090] In the example illustrated in FIG. 20, the saturation heatingeffect on the part of the rechargeable cell may be exploited, regardlessof the presence or absence of a usually closed thermo-sensitive circuitbreaker TS101 therein, to cut off the said usually closedthermo-sensitive circuit breaker TS1 that is integral with the chargingpower supply side structure and what with the ongoing heated conditionof the heat retention resistor the usually closed thermo-sensitivecircuit breaker will continue to maintain its heat-on cutoff condition.

[0091] Another aspect of the invention in the light of a dual purposecircuit is shown in FIG. 21, which provides essentially for a usuallyclosed thermo-sensitive circuit breaker TS1 integral with the chargingpower supply side structure and which forms a perfect thermocouple withthe rechargeable cell, the charging power supply being in series withthe usually closed thermo-sensitive circuit breaker TS1, one terminal ofthe power supply connected to one conductive pin of an opposite polarityrelative to the rechargeable cell B1 via conductive contact orplug/socket assembly P1, whereas the other end of the usually closedthermo-sensitive circuit breaker TS1, in series with the power supply,is connected to the output end of the usually closed thermo-sensitivecircuit breaker TS101 that is in series with the conductive contact onthe other end of the rechargeable cell B1 by way of conductive contactor plug/socket assembly P2; as to the heat retention resistor R1, ofwhich one end is connected to the common joint between the usuallyclosed thermo-sensitive circuit breaker TS1 and the charging powersupply, whereas the other end is guided to the power supply side of theconductive contact or plug/socket assembly P3, the load side of theconductive contact or plug/socket assembly P3 is guided to the commonjoint between the rechargeable cell B1 and the usually closedthermo-sensitive circuit breaker TS101, way between the charging powersupply sides of both the conductive contact or the plug/socket assemblyP2, P3, is installed a diode CR1 in the direction in compliance with thecharging current running direction, meant to allow passage of chargingcurrent in the event the rechargeable cell B1 in use is devoid of ausually closed thermo-sensitive circuit breaker TS101.

[0092] As a further variant, in the example illustrated in FIG. 21 thescheme provides for a usually closed thermo-sensitive circuit breakerTS1 on the charging power supply side which forms a perfect thermocouplewith the rechargeable cell, the charging power supply being in serieswith the usually closed thermo-sensitive circuit breaker TS1, one end ofthe power supply connected to one of a number of pins of the oppositepolarity on the rechargeable cell B1 by way of conductive contact orplug/socket assembly P1, and with the power supply accessed to the otherend of the usually closed thermo-sensitive circuit breaker TS1, and thatend being connected to the output end of the usually closedthermo-sensitive circuit breaker TS101 that is in series with conductivecontact on the other end of the rechargeable cell B1 by way ofconductive contact or plug/socket assembly P2; with one end of the heatretention resistor R1 connected to the common joint between the usuallyclosed thermo-sensitive circuit breaker TS1 and the charging powersupply, the other end thereof connected to the power side of theconductive contact or plug/socket assembly P3, the load side of theconductive contact or plug/socket assembly P3 going to the common jointbetween the rechargeable cell B1 and the usually closed thermo-sensitivecircuit breaker TS101, then, with a diode CR1 interposed in thedirection in which the charging current flows way between the chargingpower sides of the conductive contacts or of the plug/socket assembliesP2, P3, charging current will be allowed to pass in the event therechargeable cell B1 in use is not equipped with a usually closedthermo-sensitive circuit breaker TS101.

[0093] In addition, in the embodiment shown in FIG. 21, it is preferableto install, to the structure close by the usually closedthermo-sensitive circuit breaker, an auxiliary resistor Z1 which isexecuted to be one or more fixed or variable resistor or PositiveTemperature Coefficient (PTC) or Negative Temperature Coefficient (NTC)resistor, or such as is in the form of two or more differentlycharacterized resistors in serial or parallel connection or in compoundserial/parallel combination, as well as power indicator L200 whereneeded in the application, and that set in parallel with the chargingpower supply, while forming a symbiotic enclosure PK1 with the heatretention resistor R1 and the usually closed thermo-sensitive circuitbreaker TS1, or instead conjointly collocated in a totally or partiallysealed enclosure for mutual thermo-coupling, so as to produce auxiliaryheat in a low temperature charging environment, thereby minimizingimpact due to a low temperature environment upon operation of theusually closed thermo-sensitive circuit breaker TS1; or as analternative approach the auxiliary resistor Z1 may be made in serieswith the diode CR1 only to be altogether in series with the usuallyclosed thermo-sensitive circuit breaker TS1, and in that wise, madeparallel with a D.C. power supply, optionally, a display ID1 withassociated voltage restriction or current division means is made inparallel with a current divisor resistor RS, thence in series with theheat retention resistor R1, only to be parallelled across the usuallyclosed thermo-sensitive circuit breaker, or alternatively the displayID1 together with requisite voltage restrictor or current divisor ismade in parallel with the usually closed thermo-sensitive circuitbreaker TS1 across both ends, in order that once the usually closedcontacts turns open, electric energy may be way of the auxiliaryresistor Z1 drive the display ID1 integral with requisite voltagerestrictor or current divisor; so that a bypass current takes form whenthe usually closed thermo-sensitive circuit breaker cools off and thecontact resets to closure, and power to the display ID1 is suspendedaltogether, also, to prevent the rechargeable cell B1 from reversedischarge by way of the auxiliary resistor Z1, an insulation diode CR2maybe interpolated where justified in the application to serveinsulation purposes, including:

[0094] 1. forward interpolation of an insulation diode CR2 way betweenthe power supply end of the auxiliary resistor Z1 and the A.C. powersupply end enabling the rectifier RC100 installed to provide D.C.charging energy, to enable the auxiliary resistor Z1 with the D.C.required and serving also to prevent reverse discharge of therechargeable cell B1;

[0095] 2. forward interpolation of an insulation diode CR0 way betweenthe power supply end of the auxiliary resistor Z1 and the D.C. outlet ofthe rectifier RC100 as related to the charging power supply, and thatfed to the charging power supply side of the conductive contact orplug/socket assembly P1, thereby serving to prevent reverse discharge ofthe rechargeable cell B1.

[0096] By a choice made on the differential between the operatingtemperatures and temperature reception gradients of both usually closedthermo-sensitive circuit breaker TS1 and TS101, the following operationprocedures are made available:

[0097] A. In applications where the rechargeable cell B1 is not equippedwith a usually closed thermo-sensitive circuit breaker TS101:

[0101] 2. In the event the usually closed thermo-sensitive circuitbreaker TS101 for the rechargeable cell B1, affected by the heat, cutsoff in the first place, then the charging current will continue passingthe diode CR1, and that bringing about transfer of heat to the usuallyclosed thermo-sensitive circuit breaker TS1 which forms part of thestructure close by the charging power supply, such that the circuitbreaker TS1 duly affected by the heat turns open eventually, that is,whether or not the rechargeable cell is itself equipped with a usuallyclosed thermo-sensitive circuit breaker TS101, the thermal effect owingto the saturation of the rechargeable cell will suffice to open theusually closed thermo-sensitive circuit breaker TS1 which forms part ofthe structure close by the charging power supply, heating released bythe heat retention resistor R1 serves to maintain the usually closedthermo-sensitive circuit breaker to completion of charging in athermally open state.

[0102] The embodiment illustrated in FIG. 21 may be adapted to what isshown in FIG. 22 by having one end of the auxiliary resistor R101connected to the conductive contact or plug/socket assembly P3, theother end thereof set in triplicate connection together with one of theconductive pins whereby electric power is accessed to and from therechargeable cell B1, and one end of the usually closed thermo-sensitivecircuit breaker TS101, to make a perfect thermocouple with the usuallyclosed circuit breaker TS1 or TS101 or alternatively for currentrestriction purposes, as appropriate, accounting for a source of heat indischarge of thermal conservation ends, an example illustrating theinstallation of an auxiliary resistor shown in FIG. 21 to the side ofthe rechargeable cell is given in FIG. 22.

[0103] A third illustration of the dual purpose circuit pursuant to theinvention is shown in FIG. 23, with the theme being the incorporation ofa usually closed thermo-sensitive circuit breaker TS1 on the structureclose by the charging power supply side and that making a perfectthermocouple with the rechargeable cell, the charging power supply beingin series with the usually closed thermo-sensitive circuit breaker TS1,one end of the power supply connected to one of a number of pins of theopposite polarity on the rechargeable cell B1 by way of conductivecontact or plug/socket assembly PI, and with the power supply accessedto the other end of the usually closed thermo-sensitive circuit breakerTS1, and that end being connected to the output terminal of the usuallyclosed thermo-sensitive circuit breaker TS101 that is in series withconductive contact on the other end of the rechargeable cell B1 by wayof conductive contact or plug/socket assembly P2; with one end of theHeat Retention Resistor R1 connected to the common joint between theusually closed thermo-sensitive circuit breaker TS1 and the chargingpower supply, the other end thereof connected to the power side of theconductive contact or plug/socket assembly P3, the load side of theconductive contact or plug/socket assembly P3 going to the common jointbetween the rechargeable cell B1 and the usually closed thermo-sensitivecircuit breaker TS101, then, with an auxiliary resistor R101 parallelledacross the charging power supply side of the conductive contact orplug/socket assembly P2, P3, charging current will be allowed to pass inthe event the rechargeable cell B1 in use is not equipped with a usuallyclosed thermo-sensitive circuit breaker TS101.

[0104] In addition, in the embodiment shown in FIG. 23, it is preferableto install, to the structure close by the usually closedthermo-sensitive circuit breaker, an auxiliary resistor Z1 which isexecuted to be one or more fixed or variable resistor or PositiveTemperature Coefficient (PTC) or Negative Temperature Coefficient (NTC)resistor, or such as is in the form of two or more differentlycharacterized resistors in serial or parallel connection or in compoundserial/parallel combination, and that set in parallel with the chargingpower supply, while forming a symbiotic enclosure PK1 with the heatretention resistor R1 and the usually closed thermo-sensitive circuitbreaker TS1, or instead conjointly collocated in a totally or partiallysealed enclosure for mutual thermo-coupling, so as to produce auxiliaryheat in a low temperature environment upon operation of the usuallyclosed thermo-sensitive circuit breaker TS1; or as an alternativeapproach the auxiliary resistor Z1 may be made in series with the diodeCR1 only to be altogether in series with the usually closedthermo-sensitive circuit breaker TS1, and in that wise, made parallelwith a D.C. power supply, optionally, a Display ID1 with associatedvoltage restriction or current division means is made in parallel with acurrent divisor resistor RS, thence in series with the Heat RetentionResistor R1, only to be parallelled across the usually closedthermo-sensitive circuit breaker, or alternatively the Display ID1together with requisite voltage restrictor or current divisor is made inparallel with the usually closed thermo-sensitive circuit breaker TS1across both ends, in order that once the usually closed contact turnsopen, electric energy may by way of the auxiliary resistor Z1 drive theDisplay ID1 integral with requisite voltage restrictor or currentdivisor; so that a bypass current takes form when the usually closedthermo-sensitive circuit breaker cools off and the contact resets toclosure, and power to the display ID1 is suspended altogether, also, toprevent the rechargeable cell B1 from reverse discharge by way of theauxiliary resistor Z1, an insulation diode CR2 may be interpolated wherejustified in the application to serve insulation purposes, including:

[0105] 1. forward interpolation of an insulation diode CR2 way betweenthe power supply end of the auxiliary resistor Z1 and the A.C. powersupply end enabling the rectifier RC100 installed to provide D.C.charging energy, to enable the auxiliary resistor Z1 with the D.C.required and serving also to prevent reverse discharge of therechargeable cell B1;

[0112] 2. In the event that the usually closed thermo-sensitive circuitbreaker TS101 for the rechargeable cell B1, affected by the heat, cutsoff in the first place, then the charging current will continue passingthe diode CR1, and that bringing about transfer of heat to the usuallyclosed thermo-sensitive circuit breaker TS1 which forms part of thestructure close by the charging power supply, such that the circuitbreaker TS1 duly affected by the heat turns open eventually, that is,whether or not the rechargeable cell is itself equipped with a usuallyclosed thermo-sensitive circuit breaker TS101, the thermal effect owingto the saturation of the rechargeable cell will suffice to open theusually closed thermo-sensitive circuit breaker TS1 which forms part ofthe structure close by the charging power supply, heating released bythe heat retention resistor R1 serves to maintain the usually closedthermo-sensitive circuit breaker to completion of charging in athermally open state.

[0115] In addition, in the embodiment shown in FIG. 25, it is preferableto install, to the structure close by the usually closedthermo-sensitive circuit breaker, an auxiliary resistor Z1 which isexecuted to be one or more fixed or variable resistor or positiveTemperature Coefficient (PTC) or Negative Temperature Coefficient (NTC)resistor, or such as is in the form of two or more differentlycharacterized resistors in serial or parallel connection or in compoundserial/parallel combination, as well as power indicator L200 whereneeded in the application, and that set in parallel with the chargingpower supply, while forming a symbiotic enclosure PK1 with the heatretention resistor R1 and the usually closed thermo-sensitive circuitbreaker TS1, or instead conjointly collocated in a totally or partiallysealed enclosure for mutual thermo-coupling, so as to produce auxiliaryheat in a low temperature charging environment, thereby minimizingimpact due to low temperature environment upon operation of the usuallyclosed thermo-sensitive circuit breaker TS1; or as a further alternativeapproach the auxiliary resistor Z1 may be shorted from contact U tocontact V or from contact U′ to contact V′ by way of conductive contactsor plug/socket assembly P2, p3, only to come in series with the usuallyclosed thermo-sensitive circuit breaker TS1, for parallelling across theD.C. charging power supply, a display ID1 with associated voltagerestriction or current division means is made in parallel with a currentdivisor RS, thence in series with the heat retention resistor R1, onlyto be parallelled across the usually closed thermo-sensitive circuitbreaker R1, or alternatively the display ID1 together with requisitevoltage restrictor or current divisor is made in parallel with theusually closed thermo-sensitive circuit breaker TS1 across both ends, inorder that once the usually closed contact turns open, electric energymay by way of the auxiliary resistor Z1 drive the Display ID1 integralwith requisite voltage restrictor or current divisor; so that a bypasscurrent takes form when the usually closed thermo-sensitive circuitbreaker cools off and the contact resets to closure, and power to thedisplay ID1 is suspended altogether, to prevent the rechargeable cell B1from reverse discharge by way of the auxiliary resistor Z1, aninsulation diode CR2 may be interposed where justified in theapplication to serve insulation purposes, including:
